I see your point but I'm not sure whether exynos-based platforms like tensors will follow this. Afaik GS101's development name is e9845. So there likely will still be some deviation. It's not really a fatal thing, just a nit imo because all bindings will have to follow that for the upstreamed SoC, so non-revertable. But if maintainers are okay with this, I'm happy to start using chip-id names for future contributions too.
